发明名称 Dual-purpose tire inlet valve connector
摘要 A dual-purpose tire inlet valve connector has a housing, a plunger mounted in a plunger chamber in the housing, multiple steel balls mounted around a periphery of the plunger, a push post and a compression spring mounted inside the plunger, multiple plunger springs mounted between the plunger and the housing, a pressing lever mounted on a top of the housing to abut against a top end of the plunger, and a sealing collar mounted on a bottom of the plunger chamber. The steel balls can be driven by the motion of the plunger and the springs activated by the pressing lever to hold the push post or release the push post for the plunger to abut against and position an American or French tire inlet valve inserted in the dual-purpose tire inlet valve connector to fulfill a universal and fast connection therewith and a smooth air-charging job.
